Arduino uno pinout

The Arduino Uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, USB connection and ICSP header. The versatility of the pinout provides many different options such as driving motors, LEDs, reading sensors and more.

What are the 14 digital pins in Arduino?

Digital Pins: The pins 4, 6, 8, 9, 10, and 12 are used as a digital input or output for the Arduino board. External Interrupt Pins: This pin of the Arduino board is used to produce the External interrupt and it is done by pin number 0, 1, 2, and 3.

How many pins does an Arduino Uno have?

The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.

How many 5V pins are there in Arduino Uno?

The Uno has in total three power pins of which one has a supply voltage of 3.3V and two pins provide 5V.

Why Arduino Uno is used?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.

How do I connect Arduino pins?

Usually, you'll use your Arduino Uno board as the master, and you'll connect one or several components (usually sensors) to the I2C bus, with each a different ID. ... Pins for I2C

One to connect the SCL pin (clock)
Another one for the SDA pin (data)
One to power on the components on the bus.
And one to make the common ground.

Can I use pin 0 and 1 Arduino?

That's why digital pin 0 and digital pin 1 of Arduino UNO is normally avoided for the projects. But we can definitely use the digital pin 0 and digital pin 1 as a digital input-output pin after uploading the program or sketch to the Arduino board.

Why PWM is used in Arduino?

PWM Examples Providing an analog output; if the digital output is filtered, it will provide an analog voltage between 0% and 100%. Generating audio signals. Providing variable speed control for motors. Generating a modulated signal, for example to drive an infrared LED for a remote control.

What is VCC in Arduino?

(Vcc is the regulated DC supply voltage needed to operate an IC and is often referred to as a supply voltage for ICs.) Most commonly, Arduinos are designed to work at either a 3.3 V level logic for low power consumption or 5 V logic to be compatible with legacy TTL logic devices.

What is Arduino Uno full form?

"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases.

Can Arduino run on 12V?

"The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts."

Why Arduino Uno is best?

Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output.

Can Arduino Uno output 5V?

"Each of the 14 digital pins on the Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts." Ok.. this will mean operating at around 5V, but pin output won't necessarily be at 5V.

What is the max output of a Arduino Uno?

As mentioned, the maximum output current an Arduino's digital pin can supply is 40mA (or 20mA continuous current). You cannot use it to drive more than two 20mA LEDs in parallel. Likewise, the digital pin outputs 5V.

What is output voltage of Arduino?

All official Arduinos run on 5 volts, which for a long time was the 'standard' voltage for hobbyist electronics and microcontrollers. But now the coolest new sensors, displays and chips are 3.3V and are not 5V compatible. For example, XBee radios, and SD cards and acellerometers all run on 3.3V logic and power.

What is Arduino language?

What language is Arduino? Arduino code is written in C++ with an addition of special methods and functions, which we'll mention later on. C++ is a human-readable programming language. When you create a 'sketch' (the name given to Arduino code files), it is processed and compiled to machine language.

Where is Arduino used in real life?

Today Arduino is used for the control of traffic lights, it can also be used for the real time control system with programmable timings, pedestrian lighting etc.

Is Arduino a microcontroller?

Arduino (/ɑːrˈdwiːnoʊ/) is an open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.

How do I wire an Arduino?

The Build

Connect a wire from the 5V pin on your Arduino to the + column, row 30 on your breadboard.
Connect a wire from the Ground pin on your Arduino to the – column, row 29 on your breadboard.
Put the long leg of your LED in column F, row 9 on your breadboard, and the short leg in column F, row 10.

What is input and output in Arduino?

An input/output pin, or I/O pin, is the interface between a microcontroller and another circuit. In the Arduino, you configure whether a pin is an input or output using the pinMode() function. Output pins. An output pin provides VDD or 0 V, by making a connection to VDD or ground via a transistor.
